Hi everyone! I’ve recently launched Wallper, a small project I built because I couldn’t find a lightweight, native-feeling app to apply real 4K video wallpapers on macOS. You can upload your own videos (private or public), apply them to multiple monitors, and the app pauses playback in full-screen mode to save battery. I’d love to hear your thoughts, ideas, or feedback - still very early, but already live and free to try!

I built Wallper, Open-Source 4K live wallpapers app for macOS is positioned in show hn launch, a segment that rewards a clear, focused offering.

It is recorded at the Show HN launch stage.
